I do now.  GENERIC plus the options above.  Which don't make any
difference.  The box will lock up on its way into single user mode
or, if it manages to get that far, eventually during a disk access
in single user mode.  ddb is _not_ triggered.

Once the box is wedged, I can't break into ddb anymore.  At least
HALT still works.
